Abstract
An explosive welding technology for composite tool steel includes removing rust by spraying sand, mechanical polishing, heating, assembling, explosive welding, tempering, ultrasonic inspection and finishing. The used explosive contains ammonium nitrate (78-96 pts. wt.), wood powder (0.5-12 pts. wt.), diesel oil (3-10 pts. wt.), and aluminium powder (2-15 pts. wt.).
Description
The invention relates to a kind of explosion weld process and prescription thereof, more particularly about a kind of composite tool steel explosion welding technique and prescription thereof.
Make the method for stainless steel clad plate at present, mainly contain following several: 1, on the finished product steel plate with the direct composite stainless steel plate of explosion method, but because the corrosion resistant plate restriction of opening the width of cloth can only be adopted many corrosion resistant plates splicings, seam has caused surface smoothness poor, and the crack is easily arranged.2, with corrosion resistant plate and steel bad around soldering and sealing, after vacuumizing, make corrosion resistant plate and steel plate compound by heating rolling, but this method combined strength bination is low, shear strength is also very low.Do not see the report that composite tool steel is arranged up to now.
One of purpose of the present invention just provides a kind of composite tool steel explosion welding technique.
Two of purpose of the present invention just provides a kind of composite tool steel explosive welding explosive formulation.
These and other purpose of the present invention will further embody by following detailed description and explanation.
In the present invention, composite tool steel explosion welding technique and step thereof:
A, with sandblast the rust cleaning and mechanical polishing method carry out surface treatment to substrate with by substrate;
B, to handling metacoxal plate and being carried out heat treated by substrate, wherein, the substrate heating-up temperature is 60-200 ℃, the time is 5-120 minute, is 40-160 ℃ by the substrate heating-up temperature, the time is 5-60 minute;
C, assembling substrate and by substrate, the support gap that makes it the rising of front end and tail end step is 4-30mm;
D, filling explosive, it is compound to explode;
E, tempering, at 80-200 ℃, temperature retention time is 30-120 minute, normal temperature cooling then;
F, finishing, performance test.
