Description
Technical field
The invention belongs to glass manufacturing equipment, specifically a kind of new structure big pull amount calender.
Background technology
The equipment producing ultra-white photovoltaic glass is a kind of calender with upper and lower two rollers.The glass raw sheet width that calender is produced at present is typically at 2200MM(± 200MM), cutting effective width of slab is at 2000MM(± 200MM).Single line pull amount is the biggest, and glass manufacture cost is the lowest, and in order to reduce production cost, each glass production enterprise is all improving constantly pull amount.The generally pull amount of glass every day is calculated by formula below:
Pull amount D=glass raw sheet width L* thickness of glass T* pull speed S* glass density ρ
By above-mentioned formula it can be seen that the original plate width of glass directly determines the size of pull amount, the original plate width increasing glass is to increase pull amount most straightforward approach.
