General Information of Low Porosity Fireclay Brick SG12

Our corporation produces a comprehensive range of Low Porosity Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Low Porosity Fireclay bricks are the final result of blending excellent calcined flint clay and calcined bauxite, with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Low Porosity Fireclay Brick SG12

Feature of Low Porosity Fireclay Brick SG12

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining

Low apparent porosity, and low Fe₂O₃ content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion

Applications of Low Porosity Fireclay Brick SG12

Low Porosity Fireclay Brick SG12 is mainly used in glass furnace.

Q: How much is the silica powder in refractory bricks.: It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.

Q: What are the release agents of refractory bricks?: Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.

Q: how heavy are boiler of six tons plus refractory bricks?: The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material

Q: What are required for high temperature refractory bricks?: good thermal shock resistance:

Q: Which is more useful, aerated concrete block or clay brick?: How to evaluate the porous brick right (aerated concrete block), the practicability of the clay brick, brick which is first aerated concrete block, aerated concrete block and clay brick is the coexistence of wall materials, only the current use rate than the aerated concrete block of clay solid brick.

Q: Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?: ceramic fiber module is better

Q: Can red bricks be burned in tunnel kiln which used to burn refractory brick?: Of course. But the temperature to burn refractory brick is very high, the average temperature is above 1500 degrees. And the temperature to burn brick is not so high, about 1200 degrees. So you should control the temperature, the tunnel kiln to burn firebrick and the tunnel kiln to burn red brick are the same, there is just a little bit difference in the materials used to build the stove!

Q: is there any requirement for radioactive materials in refractory materials.: they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value

Q: The shape and size of general used refractory brick: According to the national standard, the outline dimension of mechanism red brick is: length is 240mm, width is 115mm and thickness is 53mm. That is: 240mm * 115mm * 53mm. The shape and size of the ordinary refractory bricks are: Length is 230mm, width is 114mm and thickness is 65mm, that is: 230mm * 114mm * 65mm. The shape and size of special refractory bricks are: 345mm*328mm*97mm.
