Description
Technical field
Cold-rolled orientation silicon steel magnesium oxide coating production technology of the present invention, belongs to silicon-steel magnesium oxide processing technology field.
Background technology
Existing cold-rolled orientation silicon steel uses the technique heated before magnesium oxide coating, adds before coating through horizontal heater
Heat, heating and temperature control is at 450 DEG C~600 DEG C, high energy consumption, and a certain amount of protective gas is passed through in stove, such as nitrogen and
Decomposed ammonia.
The content of the invention
The invention overcomes the deficiencies of the prior art, and provides a kind of cold-rolled orientation silicon steel magnesium oxide coating produces work
Then skill, i.e. cold-strip steel are washed, dried, magnesium oxide coating, gas furnace is dried, finally at end through uncoiler uncoiling degreasing
End is rolled up together through coiling machine, and compared with prior art, performance of the invention and surface quality improve significantly, and performance compliance rate carries
High by about 20%, dew brilliant phenomenon in surface prevents substantially, and energy consumption cost has but dropped about 30%.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Cold-rolled orientation silicon steel magnesium oxide coating is given birth to
Production. art, comprise the following steps：
The first step：Degreasing；Silicon steel coil after cold rolling goes to degreasing unit and carries out ungrease treatment；
Second step：Washing；Silicon strip after degreasing is washed through normal-temperature water, removes the degreasing agent in steel strip surface；
3rd step：Drying；Steel band after washing is extracted into drying oven through squeeze roll dries, and drying temperature is 50~70
℃；
4th step：Magnesium oxide coating；Enter coating machine after steel band drying and carry out magnesium oxide coating, magnesium oxide coating should be equal
Even, one side coating content is 5~8g/m2；The ratio of magnesia be pure water 600L, magnesia 80Kg, titanium dioxide 6Kg, addition
Agent 2Kg；
5th step：Steel band after coating is dried through natural gas drying oven, and in-furnace temperature is 350~500 DEG C；
6th step：Steel strip coiling；The rolling machine volume of steel band after coating solution is dried is neat, tension force 500~
900Kg。
Preferably, the degreasing process in the first step is as follows：Silicon steel coil after cold rolling is in uncoiler uncoiling, then through de-
Fat equipment carries out scrub degreasing.
Preferably, the degreasing agent is special emulsion degreasing agent.
Preferably, the concentration of the emulsion degreasing agent is 3%~7%, and degreasing agent temperature is 40~70 DEG C, unit during degreasing
Speed is 20~60m/min.
The present invention has an advantageous effect in that compared with prior art：The present invention is compared with existing method, existing side
Method is often heated using combustion of natural gas or resistive band heating to silicon strip, and energy consumption is higher during production, and natural gas or electricity make
Dosage is big, and natural gas environmental pollution is larger.And the present invention then directly save this link accomplish it is energy-saving while again not dirty
Contaminate environment.
