Q: What is the upper temperature limit for refractory materials?: Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: What is unshaped refractory?: Concrete。 Early concrete technology appears, it is not forming products in the heat furnace, some parts such as pit heating furnace furnace wall, rotary kiln mouth ring, cutting slope and discharge chamber wall, etc., are able to design large masonry (top heating block weighing 3-4 tons) made concrete. Concrete cattle production method is to pour the material into the model, vibration molding, after the release of heat treatment, to provide users in addition to large blocks, weight, in use, and machine pressure brick no essential difference. The amount of water used in the casting material produced by the manufacturer is less than 10% above that in the field, and the processing quality is good and the quality is stable. As the bricks are large and heavy, the site shall have lifting equipment. As long as the site can be hoisted, the concrete shall be used as far as possible, or smaller ones, and some people can lift it. Concrete does not require the user to do a special heat treatment, this point is very meaningful.

Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?: gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.

Q: What are the refractory materials above 1000℃: It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .

Q: What antioxidant will be used in refractories?: Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc

Q: The difference between refractory and thermal insulation material: Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.

Q: Does anyone know what is the use of waste refractory materials?: 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.

Q: What types of steel are silicious quicksand and chromium quicksand used in respectively?: Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.

Q: Who can tell me the properties and classification of insulating refractories?: Bubble method. This method is the foam agent in a frothing machine mixing with water and prepared uniform fine foam, the foam added in common mud mixing into the foam slurry injection model, together with the drying, demoulding, at 1320 DEG C to 1380 DEG C (high alumina insulating refractory brick for burning) after processing, the plastic products.
