Q: Can quantitative feeder be used in refractory plant? Thank you: Well, can the Weifang Sanyou automation equipment production chain plate feeder is fully applicable to the measurement and control of boring high temperature, chain plate feeder with 16 4-5MM manganese plate.

Q: How is grade of fire endurance divided?: Level of the building is classified according to the importance, fireproofing, durable life and etc. different angles. Civil buildings are classified according to the following ways: 1, It is divided into five grads according to its importance: A, AAA level: Buildings with great memorial, of historic, international and national level. B, A level: High-grade residential buildings and public buildings. C, B level: Intermediate residential buildings and public buildings. D, C class: Ordinary residential buildings and public buildings. 2, It can be classified into four types according to the fireproof performance: Fire resistance level of the buildings is divided into four levels. Standard of fire resistance level is decided based on the combustion performance and fire endurance of the main components of the building. 3, It can be classified into four levels according to the durable life: A, A level durable life is more than 100 years. It is applicable for important buildings and high buildings. B, B level has a endurance for 50 to 100 years and it is applicable for ordinary buildings. A, C level has a durable life of 25 to 50 years. It is applicable for less important buildings. B, D level has a lasting year of below 15 years and it is applicable for temporary buildings.

Q: What kinds of refractory will be used in kiln of sintering ceramics?: Porcelain has many classes, including acid, alkaline and neutral materials.

Q: What are the physical properties of refractory material?: The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!

Q: Who knows what kind of fire prevention materials are there?: 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.

Q: What kind of refractories do the anode baking furnace use?: Usually the clay refractory bricks will be able to meet the requirements

Q: What are the disadvantages of the refractory industry?: The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.

Q: who knows the technology of fireproofing material?: 1, Foam insulation board,it's the foam insulation board material made by inorganic ceramic material through high temperature roasting, and is called for short as ceramic insulation plate. 2, composite cement foaming insulation board is made by cement,fly-ash,silica fume and other main materials and it's a kind of hole-closed?lightweight hydrophobic insulation board made by the technologies of foam,maintenance,cutting processing. 3, gypsum foam thermal insulation board is inorganic thermal insulation board that takes industrial by-product gypsum as the main raw material, modify the gypsum through physic modified principle, then foam, casting and cutting through chemical foam principle. 4, aerated concrete panel is made by lightweight material,silicious material, foaming?agent and other raw materials and it's a kind of lightweight concrete plate material made by the high pressure steam of manufacturing technique. 5, rock wool board is made by natural igneous rock and other main materials, and it's a kind of plate with thermosetting resin as binder made through melting in high temperature and centrifugation.
