Refractories For Glass Industry Refractories For Glass Industry,Refractory Bricks,Refractory Materials,Refractory Castable Zhengzhou YuXin Kiln Engineering Co.,Ltd. ,
Kiln as the core of the glass production equipment, its technology level also in constant progress, widespread adoption of improved combustion intensity, strengthening heat transfer effect, reduce the heat loss, reducing of the product and the environment pollution and so on new technology. Kiln technology progress requires many varieties of high quality refractory materials as a condition of protection, fire-proof material can withstand higher temperature, the more rapid temperature change, strong chemical erosion, and severe stress damage, only used for many varieties of high quality refractory material, kiln new technology of high efficiency, energy saving, low pollution and other advantages to be realized. High quality refractories are not only consumable materials for modern high temperature technology, but also the functional materials necessary for high temperature new technology.
Design and application of adjustable mandrel
In production practice, we often encounter workpieces similar to those shown in Figure 1, with high coaxiality requirements for the inner and outer rings. In mass production, it is often necessary to reduce the tolerances of the inner hole before the process, and improve the positioning accuracy to finally meet the accuracy requirements of the parts. To this end, we have designed a variable diameter mandrel that does not need to reduce the tolerance of the inner hole of the workpiece. For parts with different dimensional deviations of the same specification, it is only necessary to adjust the diameter of the mandrel to achieve reliable positioning. The structure is shown in Figure 2. Show. The working process is as follows: first loosen the knuckle nut 6 to make the slider 4
