Q:what needs to be noted when choosing and using blast furnace fireproof materials?: Hello,: three parts of the blast furnace lining in general are easily corroded. The first one is furnace bosh,second is the middle part of the furnace, The third is lower part of the furnace stack. if These parts are damaged, then we need an overhaul. Bosh, because damage to the middle part of the furnace and the furnace bosh are generally due to alkali metal and fusant erosion. the main reason for the lower furnace part damage is molten iron, slag. In view of this situation, mullite bricks, corundum bricks, silicon carbide bricks are used for reparation. make repairments as soon as possible if any problems occur in case of incidents.

Q:Does anyone know the refractory temperature of fire-resistant glass?: Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. (I hope this answer can help you!) Hope you adopt !)

Q:What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q:What high-molecular polymers can be used as fire-resistant material binder?: Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.

Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: First of all, customer requirements, packaging according to customer requirements. According to the packaging packaging tray packaging is divided into 40 yuan / tons, carton 70 yuan / tons, 40 yuan / ton, straw packing bags of 30 yuan / ton.

Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.

Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?: The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.

Q:What's the heat conductivity coefficient of fire-resistant material?: There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.

Q:What dose the fireproof and thermal insulation material include?: Currently the non-combustible insulation materials for external insulation system mainly are foam insulation board, composite cement foam insulation board, aerated concrete panels, rock wool board (strip), and inorganic insulation materials. 1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.

Q:How to use fireclay?: Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.
