Q:Characteristics of refractory bricks
The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear change on reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
Q:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
Q:What are the main raw materials of refractory brick and runner brick?
Category of refractory , runner brick mainly is clay brick
Q:What is the best color of refractory brick
Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.
Q:The matching ratio of masonrying refractory bricks cement
When building refractory bricks, use matching chamotte, do not use cement
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:can the refractory sand be used to make refractory bricks?
refractory bricks can be used as a refractory sand after crushing , no strength required results in the lower intensity, but the temperature is not high, so it is not recommended, but refractory bricks after the high temperature is fine because its properties are changed
Q:How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?
1, classify according to the smelting method : Open-hearth furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...
