Description
Technical field
The present invention relates to non-crystaline amorphous metal band field, be specifically related to non-crystal belt making device and the technique of the constant molten steel liquid level of a kind of energy and temperature.
Background technology
Non-crystaline amorphous metal band is inner by being filled into system band bag (i.e. nozzle bag) after fusing molten steel, then by the nozzle (i.e. a slit) of system band bag, pouring molten steel is completed on cooling wheel.System is with the action of having wrapped to be that molten steel is forced on cooling wheel from the slit of system band bag.Because the thickness of strip product only has 25-30 micron, cooling velocity, close to each second 1,000,000 degree, goes out tape speed close to each second 30 meters, so band process processed is all very responsive to pressure, temperature and flow.For making the band thickness made consistent, the flow that just must ensure to make the molten steel that pressure temperature that is consistent, molten steel in band bag is consistent, extrusion is gone is consistent.
The band bag overview processed used in current industry is as follows:
In Stress control, usually be all realized by setting liquid level, in existing system band bag, liquid level locates highs and lows by two electrodes, just open stopper in melted steel container (tundish) when liquid level touches the bottom and mend steel to system band bag, wait reach the highest liquid level time shut stopper again and stop mending steel.Along with molten steel extrudes from system band bag nozzle (slit of namely tapping), the stopper of melted steel container frequently opens and closes, and reaches with this object controlling liquid level.
In temperature control, be all add resistance heating element in system band bag periphery usually, prevent the loss of making liquid steel temperature in band bag with this.
The shortcoming of prior art is as follows:
Shortcoming one, control liquid level by means of only long and short two root electrode in bag, liquid level is non-constant, has fluctuation, causes pressure to have deviation.
Shortcoming two, resistive element appearance heats the effect can only playing insulation, and cannot promote the temperature of molten steel in system band bag, thus impossible temperature adjustment, temperature control, lack intensification means when temperature declines in wrapping, can not reach the object of constant temperature.
Shortcoming three, flow is non-constant.The flow that molten steel flows out from slit is when slit sizes is constant, and pressure and temperature have much relations, and when pressure is large, flow is large, and pressure hour flow is little, good fluidity during temperature height, and flow is just large, and when temperature is low, fluidity molten steel is poor, and flow is just little.Because the instability of the deviation of pressure and temperature, the instability of flow will be caused.
Shortcoming four, when starting system band, when making the molten steel in band bag and not reaching the liquid level of technological requirement, molten steel has begun through slit and has flowed out, and the band now produced is scratch tape, and waste is serious.
In sum, the band bag processed used in current industry controls liquid level by wrapping interior long and short two root electrode, and pressure has certain deviation, and with resistive element insulation, without temperature control, because pressure has deviation, temperature is non-constant, and the constant control of flow is also impossible.Therefore the band thickness lack of homogeneity produced, yield rate is lower, and can produce a lot of scratch tape when start is produced, and waste is serious.
