The production process of cold rolled titanium strip is: hot-rolled strip--hot-rolled strip tailor-welded, linking—annealing—pickling--surface grinding—rolling—cleaning--vacuum annealing--leveling, straightening-- finishing, and packing.

Before cold rolling, the two ends of the strips are connected to lead strips in order to improve the yield of the finished product. The surface oxide layer of the titanium strip after hot rolling needs to be cleared by the "mechanical descaling, mixed acid pickling" process. The capacity of the single stand mill can meet the production requirements of the cold rolling of titanium strips. Because of the remarkable properties of titanium, the cold rolling of titanium strips is usually rolled with a smaller diameter work roll mill under high tension, and the final annealing must be vacuum annealing to ensure the purpose of product surface. Leveling and stretching is to make the finished titanium strip obtain a suitable surface condition and a good plate shape.

The specification of hot rolled strip for cold rolling is (3~6)mmx(600~1600)mm, and the weight of a single coil is less than 10t. The preparation of raw materials mainly consists of assembling small strips into large strips, welding lead bands, cutting and renewal of lead bands, cutting edges, etc., because the cold rolling of titanium strips generally uses reversible rolling mills, so that the ends of the strips are part of the head and tail. If it cannot be rolled normally, the titanium material will have a greater waste. Therefore, the guide belt must be connected at both ends of the strip before cold rolling to increase the yield of the finished product and reduce the production cost. When the material of the lead tape and the strip blank are both pure titanium, butt welding connection is used, but when the material of the lead tape is not pure titanium (such as stainless steel, etc.), since direct welding cannot be carried out, it must be connected by mechanical riveting. The lead strip must be removed at the end of rolling. The lead strip can be used repeatedly. The raw material preparation stage requires a strips assembly unit to assemble small hot-rolled strips into large strips. The hot-rolled strips are welded on the leading strips, and the titanium strips after the intermediate rolling are welded. Carry out the excision of the original lead tape and weld the appropriate new lead tape. In order to make the lead tape reusable, it is necessary to set up a lead straightening unit, which is used to straighten and cut the head and tail of the used lead tape, and to manufacture new lead tapes.
