Product Description Product DescriptionPericlase chromite porous purge plug for copper smeltingIn steel-making today, gas blowing in a ladle is indispensable for improvement of steel quality and for continuous casting.SNREF purging plug is characterized by their high strength, good erosion resistance and corrosion resistance, high blowing rate and good safety. They are widely used for continuous casting ladles and refining ladles.Hot Sales Types-Slot Plug(slit plug)Slot plug is the most common structure in purging plug.The gas channel could be designed and customized according to actual on-site using conditions, including refining steel grade, refining workmanship, ladle capacity, temperature, hydrostatic pressure of liquid steel etc.This can achieve the best blowing effect for purging plugs, ensure the longest service life, safety, stability and best air permeability.-Porous plugPorous plug has better porosity and permeability.Production technology is adding carbon-containing compound into mixture, since carbon-containing compound can burn out withoutresidue at low temperature, so we adopt low temperature burning out intermediate materials to get the initial porosity.In porous type plug, inside distributes interpenetrating gas channels in different sizes.When blowing stop, the steel and slag from ladle will infiltrate into the deep areas of the plug, to form a secure layer on working surface.-Segment PlugThe segment plug is preferably made of good anti-stripping materials, the block body is not easy to occur fracture, with longer service life. The cracks between different plates will not expand, so this segment plug design can avoid failure of bottom blowing caused by tranverse brick fracture.Application characteristics: In order to adapt to more and more strict refining conditions(especially special steel), and to meet the requirements of increasing ladle life, the volume of plug becomes bigger and bigger. However the traditional slit type plug has single material and single structure, easy to cause the phenomenon of tranverse fracture and failure of air blowing. Our researched segment plug has successfully soved the problem of fracture existing in traditional slit plug. Significantly increasing the stability of refining process, ensuring the realization and improvement of quality refined steel.-Hybrid PlugSecondary refining technology is the most important part in steelmaking process.It can adjust the steel alloy type and liquid temperature.Purging plug and block is the key functional component to make this process carried out.As the ladle tends to develop in larger scale, the melting temperature and time have been improved significantly, which makes the using environment for refractory materials more and more strict. Therefore, it is necessary to further improve the performance of purging plugs and blocks to meet the increasing demands in current steelmaking technology.-Overall breathable brick:This product adopts high purity raw materials, through vibration casting and low temperature heating process workmanship.Function is blowing argon gas via purge plug to ladle.With the feature of high strength, good thermal stability, erosion resistance and abrasion resistance.Widely used in steel plants LF, LF-VD, CAS-OB refining ladleWe manufacture various high-quality ladle refractory according to the clients' needs , and to ensure the stability and accountability of the quality.Product ParametersTechnical data will be customized according to your steel making condition.Chemical and Physical PropertiesSNLWB-85SNLWB-90SNLWB-95Al2O3 +MgO % min859095Cr2O3 (C) % min02.52.5Apparent porosity g/cm3% max151313Bulk density g/cm3 % min3.03.052.9Normal temperature Compressive strength (MPa) min80100100Breaking strength 1500°C×3hmin23Mpa 2.Well block and segment plugChemical and Physical Properties(Well block)(purging plug)AL2O3 %>=85>=85MgO%3-51-3Cr2O3 %----->2.4Bulk density g\cm3>=3.0>=2.9Apparent Porosity %<=16<=18Cold crushing strength Mpa110oC*24h>=60.0>=80.01500oC*3h>=100.0>=80.0Refractoriness under load : oC>=1680>=1680Modulus of rupture 1400oC *1h Mpa Mpa>=15.0>=15.0Linear change 1500oC*3h %±0.2±0.2air permeability, m3/hour at P=4 bar30M3/HPackaging & ShippingProduct packaging1- International standard seaworthy exportable packing.2- Wooden pallet.3- Wooden / bamboo case (box).4- Further packing information will be based on customer's requirements.Company ProfileShandong Sinorefractory New Materials Co.,Ltd (SinoRefractory)has been focusing on international marketing of flow control refractories in iron and steel industry for 18 years.SinoRefractory is the second generation of refractories export enterprise developed out of EMEI Group.Supported by one of China's largest production bases in functional refractory materials.Through years of development in the field of exporting top quality refractories to worldwide markets,SinoRefractory aims at researching,producing,marketing and exporting high standard Ladle slide gate plate,Ladle Nozzles,Well blocks,Purging plugs,Nozzle stuffing sand,Refractory castables, Slide gate Mechanisms etc.Up to now,SinoRefractory has supplied high quality refractory products and services to nearly 70 top-hundred global steel enterprises.In order to expand into broader product areas and position itself as a leading supplier of high-end refractory materials, SinoRefractory became an affiliated enterprise of Sinosteel Luoyang Institute of Refractory Research. Following the establishment of this strategic partnership, SinoRefractory has made significant progress in new product development, technical support, and market expansion.SinoRefractory will always put clients'interest in the first place,striving to provide a wide range of services,including technical solution,pre-sales support,after-sales services,installation team support,professional know-how according to the changing of steelmaking condition,etc.We are not only selling products,we are more focused on supporting,developing and growing together with clients.SinoRefractory is committed to become the leading company on exporting premium quality Made in China functional refractories to global markets. Establishing "SNREF" as the definitive brand in steelmaking flow control refractory materials.Our AdvantagesOur Advantages of SNREF Ladle Gas Purging System Purge Plug Set Block for Steel Melt RefiningWear resistant materials to cope with high local turbulence and with consistent dimensional control to fit the purge plug.Purge Plugs: * Uni or omnidirectional, porous or with slots, several designs * Large material portfolio to select with our specialistsPlug and Block Assemblies (PBA) reduce your installation challenge and risk.FAQBelow are some RFQ and answers about ladle and tundish flow control refractories:Q: What are the requirements for refractories for ladle?A: The requirements of refractories for ladle mainly include: * high temperature resistance * thermal shock resistance * resistance to the erosion of the slag * high temperature with sufficient mechanical strength * the lining has a certain degree of expansionQ:What are the reasons for the destruction of refractories for ladle?A: The main causes of damage are as follows:When the ladle transports high-temperature molten steel, the high-temperature molten steel and slag at about 1680oC scour and erode it, especially in the slag line part, the scouring and erosion is more serious, and it is an important factor to decide the service life of the ladle.LF and other extra-oven refining treatment on the unburnt brick damage is serious.Q:What steel grades are different materials of slide plate bricks suitable for respectively?A: Different materials of slide plate bricks are applicable to different steel grades. For example, Al2O3-ZrO2-C slide gate plate can be used as ladle sliding gate plate due to its excellent erosion resistance and thermal shock stability, which can adapt to the casting of various steel grades, and ther are the following materilas based on customer's steel making condition: the MgO-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, and so on.
