Problems solved by technology

The characteristic of this process is that only steel ball grinding wheels can be installed in the kiln alone during firing, and ordinary ceramic grinding wheels cannot be mixed, because the highest firing temperature is different, and the firing temperature of steel ball grinding wheels is higher than that of ordinary ceramic grinding wheels. temperature
In this way, the actual loading space in the kiln is insufficient, resulting in waste. At the same time, due to the high firing temperature and long firing time, energy is wasted, and the production cycle for small batches and special specifications of grinding wheels is long, which is not conducive to timely delivery.

Abstract

The invention discloses a firing method for a steel ball grinding abrasive wheel. Roasting is carried out in a common kiln. The method is characterized in that the roasting process is divided into five temperature rise intervals, the highest firing temperature is 1200DEG C, and the temperature rise speed and temperature rise time of each temperature rise interval are specifically designed. The method is used for production of vitrified bond steel ball grinding abrasive wheels, saves energy, also improves the product quality, can be fired together with ordinary vitrified abrasive wheels in one kiln, and is conducive to enhancing economic benefits and market competitiveness.

Description

technical field [0001] The invention relates to the manufacture of a vitrified bond grinding steel ball grinding wheel, in particular to a firing method for grinding steel ball grinding wheels. Background technique [0002] Steel ball grinding wheel is a special grinding wheel for grinding spherical steel balls with a diameter below 76.20mm. It has the characteristics of large size, fine particle size, high hardness, and high density. It is widely used in machinery and bearing industries. Before use, the grinding wheel is fastened to a special metal chuck with adhesive. One end surface of another cast iron platen is cast with many concentric grooves, which act as a guide rail, so that the steel balls to be ground are rolled and ground in the grooves. The width and depth of the grooves depend on the diameter of the steel balls. There is a gap in the radial direction of the pressure plate leading to the slideway for the steel ball to enter and exit the grinding area. Before ...
