Description
Technical Field
The utility model relates to a diamond-impregnated wheel edging platform.
Background
A fused zirconia-corundum brick for glass kiln is prepared through such technological steps as making sand mould, smelting raw materials in electric arc furnace, pouring in liquid, filling insulating material, covering, annealing in insulating region, demoulding to obtain blank brick, and grinding with diamond grinder to obtain brick shape. Diamond grinding tool (emery wheel) is when grinding the blank brick, and diamond grinding tool has not sharp state, the not sharp reason of diamond grinding tool: the diamond grinding material is formed by mixing and sintering most of iron powder, diamond sand and a small amount of other metal powder, wherein the iron powder wraps the diamond sand, before the diamond grinding material is used, a clay brick is needed to be used as a knife stone, the iron wrapping the diamond sand is removed to expose the diamond sand, at the moment, the diamond grinding material is in a sharp state, after the diamond grinding material is used for a period of time, the diamond sand is lost, the grinding material is not sharp, the clay brick is needed to be repeatedly used to remove the iron, the diamond sand is exposed to reach the sharp state, and the process is called edging.
The grinding amount of a green brick is generally 5mm in thickness and 4 faces, the average area is about 1 square meter, so that the brick grinding powder is 18-20 kilograms, and 150 square meters are processed every day, so that about 3000 kilograms of the brick grinding powder can be generated.
No matter use the clay brick to open a knife or grind the brick to diamond grinding apparatus, all need use the shower water to cool down to it when grinding, otherwise the operation can rub under the high-speed operation of grinding apparatus and generate heat, burns out the grinding apparatus, and the clay brick powder that grinds down, the setting pit that flows into together of brick powder of grinding, the brick powder of grinding has just become solid rubbish with the clay brick powder is mixed together in the setting pit, if pure brick powder of grinding, then the brick powder of grinding has very big reuse value, for example continue to do the electric smelting brick raw materials, do the coating main material, do floor tile glaze and so on.
One brick grinding device needs 20 kg of clay bricks for edging every day, and the amount of the clay bricks for 30 devices is 600 kg every day.
The operation states of the cutting edge of the clay brick and the grinding of the rough brick are all forward operation, so that the flatness of the diamond grinding tool is restricted, the flatness of the ground brick is poor, the service life of the glass kiln can be influenced when the glass kiln is used, and the grade of the electric melting brick is reduced.
The current grinding state of the blank brick grinding workshop can cause great discount on the recycling value of the ground brick powder and great consumption of clay bricks every day.
In view of the above, the grinding state of the current grinding tool needs to be improved.
