The porous infrared ceramic block is provided with a porous infrared ceramic block, characterized in that: an annular convex surface is arranged on the upper end surface of the ceramic block, and the advantage of the utility model is that the annular convex surface plays The function of the ribs improves the mechanical strength of the infrared ceramic sheet, which can reduce the bursting phenomenon; increases the surface area of the infrared ceramic sheet and increases the heat load; the combustion flame is not at the same horizontal line, and the wind resistance at low fire is improved. The infrared release angle can be released upward from the past plane, and becomes a dual release of focusing and dispersion, which improves the thermal efficiency of the burner, is not easy to temper, and is applicable to a wider range of gas sources.

The precision roll (Fig. 1) is mainly used for rolling condensing tube, the quenching hardness is 55~58HRC, the material is Cr12MoV, and the conventional finishing process of the working surface is grinding. Now we use ceramic tools to perform fast turning on full-function CNC lathes, which realizes the grinding by the car, the processing precision is high, and the processing efficiency is improved by 5-10 times. The precision machining of this precision roll working surface is described below.
