Billet, Tube Mold Explosive Forming Technology Pilot Study

The mould is the critical component of the high efficiency continuous caster like theheart of the body. To improve the efficiency to transmit heat and the service life and makecontinuous caster achieve high drawing speed, the inner surface shape of mould isrequired to accord with the solidification and shrinkage regulation of steel water. So thedimension tolerance and inner surface glossiness and inner shape of the mould must beexacting and its traditional mechanical process is quite difficult. The explosive formingtechnique have such features as high efficiency, energy saving, low costing, high precisionetc and the applied foreground very much.In this paper, the explosive forming technique of the quadrate tube mould is fartherstudied in experiments on base of previously experiments. The main research work of thispaper is as follows:(1)With adopting the semi-finished product copper tube for the first time, theexperimental principle and ways of the explosive forming technique of tube mould isexplored, and many problem of the emergence are resolved.(2)On base of the characteristic of the explosive forming, the experiment of themode to set explosive is done and the favorable result is achieved.(3)The formula to calculate amount of the explosive is brought forward and will beperfect in farther experiments, through the forming energy and explosive charge of thequadrate tube mould are analyzed.(4)The farther experiments and problems of explosive forming technique of thequadrate tube mould and its applied prospect are evaluated.The study result: with the explosive forming technique the mould may achieveaccuracy higher size and good inside surface and the raise of the strength and the hardness.So the service the life of the mould and the high drawing speed of continuous casterachieve. This experiment study will be basic of making use of the explosive formingtechnology to batch produce.
