Abstract
The invention discloses a grinding roller shock absorption grinding wheel adjustable in hardness. Composition of the grinding roller shock absorption grinding wheel comprises white fused alumina, single-crystal corundum, black silicon carbide, phenolic resin liquid, phenolic powder, epoxy resin, sodium salt, ice crystal powder, and pyrite ore powder. The grinding roller shock absorption grinding wheel utilizes dissolution action of water in cooling liquid on the sodium salt in the composition of the sand wheel, and controls dissolution speed of the sodium salt by controlling cooling liquid flow. The strength of resin binder bonding grinding material is gradually reduced in the process that the sodium salt is gradually dissolved by water. The purpose of reducing the hardness of the sand wheel in a controllable mode can be achieved in the process. The grinding roller shock absorption grinding wheel is adjustable in hardness and strong in universality, greatly reduces the number of grinding roller grinding machines configured by a user, simultaneously greatly reduces labor amount and auxiliary work hours for frequent replacing of grinding wheels, and is favorable to improving production efficiency of grinding and cutting rollers.
Description
Technical field
The present invention relates to a kind of grinding materials and grinding tool, particularly the adjustable mill roll Shock absorbed grinding wheel of a kind of hardness.
Background technology
Require very highly for the manufacture of the plate surface quality of car crust, its surface quality depends primarily on roller surface quality used when rolling.Roll in mangle directly contact with the institute rolled steel plate, and there are the trace wearing and tearing in the operation of rolling, must do reconditioning and could continue use, reconditioning employing cylindricalo grinding technique when roll wear reaches a certain amount of.Roll on mangle has dividing of king roller, backing roll and carry-over pinch rolls, and because function is different, material used has very large difference.The metal material hardness difference of different cultivars is larger, and the emery wheel that the different rolls of reconditioning need configure the hardness that adapts just may obtain prospective quality.If the roll hardness of reconditioning does not mate with the Wheel hardness that configures, produce the trace vibration in grinding process, roller surface after reconditioning leaves visible oscillation mark, these have the roll of visible oscillation mark to be used for rolled plate, oscillation mark must be imprinted on product surface, directly reduce institute's rolled steel plate surface quality grades.
Summary of the invention
The present invention immobilizes mainly for the mill roller abrasive wheel monomer hardness of prior art, the problem that versatility is poor, propose a kind of at the adjustable grinding roller Shock absorbed grinding wheel of grinding process hardness, this emery wheel component rationally, make easily, grinding ratio is large.
The present invention is achieved through the following technical solutions technical goal.
The mill roll Shock absorbed grinding wheel that hardness is adjustable, its improvements are that the components based on weight percentage amount is as follows:
White fused alumina 45%～60%
Single alundum 5%～20%
Black silicon carbide 5%～15%
Liquid phenolic resin 2%～4%
Phenol-formaldehyde resin powder 5%～8%
Epoxy resin liquid 0.5%～3%
Sodium salt 4%～8%
Cryolite powder 2%～10%
Troilite powder 2%～10%.
The salt of receiving in said components is sodium carbonate, or sodium sulphate, also can use sodium chloride.
As further improvement project, the salt of receiving is the mixture of sodium carbonate, sodium sulphate and common salt, and mixing is measured as follows by weight percentage: sodium carbonate 10%～40%, sodium sulphate 30%～60% and common salt 20%～50%.
The present invention compared with prior art has following good effect:
1, combination is reasonable, and raw material is easily purchased, and production technology is easy.
2, the water in cooling fluid plays dissolution to the salt of receiving in the emery wheel component during grinding roller, controls coolant rate and just can control and receive the salt dissolution velocity.Receive salt by water course of dissolution progressively, being exactly resinoid bond reduces process, the purpose of the controlled reduction Wheel hardness of this process implementation to the adhesion strength of abrasive material.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
The mill roll Shock absorbed grinding wheel that hardness is adjustable, its components based on weight percentage amount is as follows: white fused alumina 45%～60%, single alundum 5%～20%, black silicon carbide 5%～15%, liquid phenolic resin 2%～4%, phenol-formaldehyde resin powder 5%～8%, epoxy resin liquid 0.5%～3%, sodium salt 4%～8%, cryolite powder 2%～10% and troilite powder 2%～10%.
Verify the present invention below by the different embodiment that adjust the component deal.
The mill roll Shock absorbed grinding wheel embodiment component deal allocation list that hardness is adjustable:
Annotate: embodiment 4 salt of receiving used is the mixture that sodium carbonate, sodium sulphate, sodium chloride respectively account for 1/3rd amounts.
The component of above-described embodiment has been done corresponding adjustment in allowed band, all reaches the prospective quality index, and wherein embodiment 3 is best proportionings.The present invention does not have special requirement to moulding process, just can realize producing with conventional moulding process.Totally 4 of embodiment, under equal working condition, grinding material respectively is the roll of high chrome, carbon steel, cast steel, regulates wheel face hardness by the flow of regulating cooling fluid in grinding process.Because the present invention regulates Wheel hardness by cooling fluid in grinding process, being easy to do is complementary with the mill roll hardness, and grinding process can vibration-generating, so accomplish that easily grinding efficiency is high, grinding ratio is large, after grinding, roller surface is bright and clean, without oscillation mark.Highly versatile of the present invention greatly reduces the quantity that the user configures roll grinder, also greatly reduces the amount of labour and the unproductive time of frequent replacing emery wheel simultaneously, is conducive to improve the production efficiency of grinding roller.
