Fused alumina zirconia abrasive material cooling device

Abstract

The invention provides a fused alumina zirconia abrasive material cooling device comprising a plurality of cooling plates. Through pin holes are formed in the upper portions of the cooling plates. The cooling plates are strung in a string through pin shafts in the pin holes. A boss is arranged on one plate face of each cooling plate, and grooves are transversely formed in the manner that the grooves and the bosses are arranged in a staggered manner. An arc-shaped cover cap is arranged above the cooling plates in a string, wherein the length of the arc-shaped cover cap is larger than the length of the cooling plates in a string; the height of each single cooling plate ranges from 530 mm to 550 mm, the width of each single cooling plate ranges from 280 mm to 300 mm, and the thickness of each single cooling plate ranges from 30 mm to 35 mm; the thickness of each boss ranges from 3 mm to 5 mm, and the depth of each groove ranges from 1 mm to 1.5 mm; the cooling plates and the arc-shaped cover cap are made from materials conducting fast heat conducting and absorbing much heat; the materials conducting fast heat conducting and absorbing much heat comprise 8%-10% of nickel, 5%-6% of chromium and the balance stainless steel. When the fused alumina zirconia abrasive material cooling device is used, because the cooling plates are strung in a string through the pin shafts by means of the pin holes, fused alumina zirconia abrasive material semi-finished products can be scattered and fall in cooling ponds by a mechanical hoisting shaft in a shaking manner, operation is convenient, fast and safe, manpower and material resources are saved, and time for cleaning one cooling pond is shortened.

Description

technical field [0001] The invention relates to a production device of zirconium corundum abrasive, in particular to a cooling device for zirconium corundum abrasive. Background technique [0002] Zirconium corundum abrasives were successfully developed in the 1960s, and my country began to produce them in the late 1990s. During this period, the core technology that affects the quality of zirconium corundum abrasives - the rapid cooling process, has not been a good solution. [0003] At present, the cooling method is generally adopted, that is, multiple cooling plates or thousands of steel balls are placed in a cooling pool, and then the zirconium corundum abrasive solution is directly poured into the center of the cooling plate or the center of the steel ball for cooling. It was found that the cooling speed was slow, and it was very troublesome to clean and collect. The weight of each small cooling plate reached tens of kilograms, and the steel plate was easily deformed whe...

[0002] Zirconium corundum abrasives were successfully developed in the 1960s, and my country began to produce them in the late 1990s. During this period, the core technology that affects the quality of zirconium corundum abrasives - the rapid cooling process, has not been a good solution.

[0003] At present, the cooling method is generally adopted, that is, multiple cooling plates or thousands of steel balls are placed in a cooling pool, and then the zirconium corundum abrasive solution is directly poured into the center of the cooling plate or the center of the steel ball for cooling. It was found that the cooling speed was slow, and it was very troublesome to clean up and collect. The weight of each small cooling plate reached tens of kilograms. The steel plate was too large to be easily deformed, and the product quality could not be guaranteed.

One shift can't clean up the finished products of a cooling pool, so it is a waste of manpower and material resources, and the finished product rate is only 70%, which is not conducive to safety
