Produce Processing 

Crushing

In this stage massive raw materials which have been stored, are ground and classified into proper sizes, making them easier to shape.

Mixing

The prescribed size of ground raw material is weighed and mixed into a designated amount of water and forming agent.

Shaping

The mixture is then poured into a mold to form shapes, and the pressure is high.

Drying 

In this stage water is removed from the shaped bricks. This helps preventing the bricks from deforming or cracking which may result due to the rapid evaporation

Firing 

This is the most crucial process in refractory manufacturing. The modeled bricks are fired at high temperature to complete their thermochemical reaction so that they do not deform.

Inspection 

The bricks' physical and chemical properties are inspected very carefully by rigid quality management procedures.

Packing shipment

We guarantee efficient delivery every time.

Q:can Methanol burn refractory brick?
Generally speaking, all the fuel can burn, mainly to see the calorific value and consumption ratio
Q:what is application of high alumina refractory brick?
reverberatory furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica brick. the refractoriness of high alumina brick is higher than fireclay brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
Q:does furnace use refractory cement to make refractory bricks?
You can use fireclay, refractory cement is commonly used to arch. fireclay has good viscidity, it is handy to use.
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:does 90m high reinforced concrete chimney need firebrick?
The chimney need firebricks or casting fire or acid resisitant concrete after casting, one aim is to resist high temperature, then is to resist acid corrosion. there is a variety of models of the refractory brick , you can refer to the installation quota.
Q:How to wipe off the white paint on the refractory brick (red).
Wallpaper knife should be ok
Q:What should be paid attention when the refractory brick kiln furnace reaches a certain service life and will be removed?
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:Is the waste of the fire resistant hazardous waste?
Refractory waste should refer to the used refractory material, which more or less have some pollution. low grade material such as clay brick and high alumina brick can be used repeatedly on the spot, such as breaking it and making it into waste refractory bricks sand, unshaped refractory meterial or low-grade refractory brick, or just bury it in a pit. collect high grade bricks such as corundum brickand silicon carbide brick and sell, they are sought after, the price per ton ranges from several hundred to several thousand. pay special attention not to dispose waste refractory bricks containing metal chromium at random, for it is toxic and carcinogenic. Collect them and seal them up, looking for manufacturers to buy and reuse.
Q:Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?
Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
