At the same time, we have 7 automatic crushing lines, such as roller and Bamac, 6 sets of Raymood mills, 4 sets of wind scrubbing, 1 medium and high temperature calcining line. The annual output of all kinds of refractory is about 60000 tons, which can provide all kinds of brown fused alumina and bauxite for refractory and abrasive.
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
WO2015100020A1 - Method of making a coated abrasive article
The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing.

The second course is laid at a 45 angle to the first course and dry magnesite mortar again is swept into the joints. This process is repeated for three or four flat courses. (There is an alternate, less preferable, sub-hearth design which lays two to four flat courses which follow the curved contour of the steel shell.
Some embodiments of the present invention include glass-ceramics comprising a first complex Al 2 O 3.Y 2 O 3, a second, different complex Al 2 O 3.Y 2 O 3, and optionally crystalline ZrO 2, and wherein for at least one of the first complex Al 2 O 3.Y 2 O 3, the second complex Al 2 O 3.Y 2 O 3, or the optional crystalline ZrO 2, at least 90 (in
