Black Silicon Carbide Powder Price 3-5mm SiC 98.5% with Best Price/China Manufacture

1.Structure of Silicon Carbide Description

Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.

Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.

2.Main Features of the Calcined Bauxite

Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.

3.Main usage of the Calcined Bauxite

1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

2.Bonded abrasive tools, lapping and polishing

3.Widely used as a metallurgical additive and refractory material

4.Refractory

6.FAQ of Calcined Bauxite

1). Q: Are you a factory or trading company?

A: We are a factory.

2). Q: Where is your factory located? How can I visit there?

A: Our factory is located in Ningxia, China. You are warmly welcomed to visit us!

3). Q: How can I get some samples?

A: Please contact me for samples

Q:The manufacturing technique of refractory material: Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank

Q:What are the new refractories?: There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543

Q:How many kinds of fireproof materials are there in the market?: A-level materials are the best which will not burn while the B-level materials are made of combustible materials which can burst into flames.

Q:What is refractory aggregate?: Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.

Q:Procedures for producing common refractory materials?: The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.

Q:What are grades of refractory materials?: Refractories have lots of varieties which all have different purposes.1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ to 1770 ℃, advanced refractories: 1770 ℃ to 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.

Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?: Different fire resistant ratings of buildings require different fire endurance of different elements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level.

Q:What is high alumina refractory?: It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.

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.
