Steel blank grinding abrasion wheel adopting microcrystal ceramic bonding agents

Abstract

The invention relates to a steel blank grinding abrasion wheel adopting microcrystal ceramic bonding agents, which is in a structure made of polycrystalline solid materials with the coexistence of glass and crystals and adopts the bonding agents of clay, feldspar, boron-containing microcrystal glass, pyrophyllite and soapstone to be made into high-intensity and low-shrinkage engineering ceramic bonding agents, good performance of the glass and the ceramics such as high mechnical intensity, wear resistance, corrosion resistance and the like are integrated, then, the glass and the ceramics are combined with mixed grinding materials, a molding pressing method is adopted for the high-pressure double-side pressing process forming, the low-temperature firing is adopted, the positive pressure reducing atmosphere heat simulation crystallization is adopted at the 800 DEG C heat insulation section, and the mixed grinding material and micro porous glass phase high-intensity microcrystal engineering ceramic composite structure is formed, so the intensity and the bonding degree of the steel blank grinding abrasion wheel are greatly improved, the use linear speed of the abrasion wheel is accelerated, and the safety factor is high. The steel blank grinding abrasion wheel belongs to the novel efficient special steel blank grinding abrasion wheel with the characteristics that the intensity andthe hardness are high, the tissue density is uniform, the grinding ratio is great under the condition of high-speed grinding, workpieces can not be damaged through firing, and the automation of iron and steel industries is easy to realize.

Description

technical field [0001] The invention relates to a formula and a manufacturing process of a microcrystalline ceramic bond grinding steel billet grinding wheel. Background technique [0002] Grinding wheel is an important tool in machining, it relies on bonding agent to combine loose granular abrasives together. Since the grinding wheel is subject to a large impact force and needs to rotate at a high speed during grinding, its strength is the premise to ensure safe and effective use; the grinding performance and efficiency of the grinding wheel are the key, and steel is an important part of modern machinery and industrial equipment. The quality of the grinding material of the steel grinding wheel is particularly important to promote the technological progress of steel production enterprises and promote the development of the industry. In the past, the bonding agents used to prepare grinding steel grinding wheels include ceramics, glass, etc., among which ceramic bonding agents...
