Abstract
A method for rapid pumping out is characterized in that cooling water of a vacuum pump system is kept unchanged, cooling water in a furnace chamber system is switched into warm water with the temperature of 50 DEG C, volatilization of molecules in a furnace chamber is accelerated, and accordingly the pumping-out speed is increased. The method has the beneficial effects that the long-time practice verifies that pumping out is carried out through the method, equipment cannot be damaged, and the pumping-out time can be effectively shortened by 3-5 hours; and the power usage amount of pumping out is saved, the production period is shortened, the work efficiency is improved, and the benefits of enterprises are greatly increased.
Description
Technical field
Patent of the present invention belongs to EB stove vacuum melting field.
Technical background
In EB stove normal productive process, often complete the melting of a heat, just need to carry out prepurging, find time re-starting after prepurging completes, after vacuum reaches melting condition, then carry out melting.During prepurging, whole furnace chamber is all be exposed among air, and due to the characteristic of titanium, the volatile matter in furnace chamber and body of heater are easy to the moisture absorption, these are attached to moisture in furnace chamber can finding time to cause and affect significantly next stove, therefore before starting to find time after prepurging completes, we first can carry out the baker of 8-10 hour, and baker is exactly by Water heating system, is passed in body of heater by the warm water of 50 DEG C and circulates, fire door need be opened simultaneously, is dried by moisture.Before starting to find time, again warm water is switched to cooling water, close fire door, then start to find time.Due to the impact of rhythm of production, the time of baker can only control at 8-10 hour, and all moisture all can not be dried like this, the speed of finding time still can be affected significantly.
Summary of the invention
The present invention is by research, invents a kind of under the prerequisite not affecting rhythm of production and device security, accelerates the method for speed of finding time.
A method for rapid evacuation, is characterized in that, keeps vacuum pump system cooling water constant, the cooling water of furnace chamber system is switched to the warm water of 50 DEG C, accelerates the molecule volatilization in furnace chamber, thus accelerates speed of finding time.
The invention has the beneficial effects as follows:
Through long practical proof, make to find time in this way, not only can not cause any damage to equipment, and effectively evacuated time can be shortened 3-5 hour, save the power consumption of finding time, shorten the production cycle, improve operating efficiency, increase considerably the benefit of enterprise.
Detailed description of the invention
Through repeatedly studying, and done test repeatedly, I finds to supply water to vacuum pump system and furnace chamber system separately, therefore, I only starts a cooling water pump, allows it only supply vacuum pump system, in order to cooling vacuum pumping system, furnace chamber system then uses Water heating system to pass into warm water baker, so just can realize baker and find time to carry out simultaneously.
Specifically in this way: after prepurging completes, still carry out the baker of 8-10 hour, when starting to find time, the warm water of furnace chamber need not switch to cooling water, only need independent Cooling Water to vacuum pump system, then can start normally to find time, when vacuum reaches condition, before preparing to start electron gun, then the warm water of furnace chamber is switched cooling water.
Why prepurging complete after still to carry out the baker of 8-10 hour, and then find time in baker limit, limit, instead of find time in baker limit in limit at the very start, because when just having started baker, the moisture volatilized is very large, if these moisture enter into vacuum pump system and can cause vavuum pump and damage significantly, so this is an obligato process.
