Embodiment 1

[0042] Titanium H-shaped bar is rolled on the small and medium-sized section steel production line, the grade is TA1, and the specification is H100×100×6×8. The production process is as follows:

[0043] 1) Billet preparation: Calculate the required billet length according to the specifications and length of the rolled product, and the surface quality of the billet should meet the production requirements;

[0044] 2) brushing protective coating: brushing protective coating on the surface of the blank;

[0045] 3) Heating: use the roller table to transport the billet to the box-type resistance heating furnace for heating, the heating temperature is 930°C, and the holding time is 160min, and then the billet is conveyed to the rolling mill area by the conveying roller table.

[0046] 4) Rolling line preheating: Before rolling titanium materials, roll 5 hot-rolled H-beams of the same specification to preheat the rolling line and adjust the specifications and dimensions of the hot-...

Embodiment 2

[0056] Rolling titanium H-shaped bar on the small and medium-sized section steel production line, the grade is TC4, and the specification is H150×150×7×10. The production process is as follows:

[0057] 1) Billet preparation: Calculate the required billet length according to the specifications and length of the rolled product, and the surface quality of the billet should meet the production requirements;

[0058] 2) brushing protective coating: brushing protective coating on the surface of the blank;

[0059] 3) Heating: The billet is transported to a box-type resistance heating furnace for heating with a roller table. The heating temperature is 1100°C and the holding time is 150 minutes. Then, the billet is transported to the rolling mill area by the conveying roller table.

[0060] 4) Rolling line preheating: Before rolling titanium materials, roll 5 hot-rolled H-beams of the same specification to preheat the rolling line and adjust the specifications and dimensions of the h...

Embodiment 3

[0070] Titanium channel profiles are rolled on the small and medium-sized section steel production line, the grade is TA1, and the specification is [80×43×5.0×8.0]. The production process is as follows:

[0071] 1) Billet preparation: Calculate the required billet length according to the specifications and length of the rolled product, and the surface quality of the billet should meet the production requirements;

[0072] 2) brushing protective coating: brushing protective coating on the surface of the blank;

[0073] 3) Heating: use the roller table to transport the billet to the box-type resistance heating furnace for heating, the heating temperature is 930°C, and the holding time is 160min, and then the billet is conveyed to the rolling mill area by the conveying roller table.

[0074] 4) Rolling line preheating: Before rolling titanium materials, roll 5 hot-rolled channel steels of the same specification to preheat the rolling line and adjust the specifications and dimensi...

Abstract

The invention discloses a collinear production method for titanium and titanium alloy profiles and profile steel. In the collinear production method, the method for producing titanium and titanium alloy profiles is to firstly coat titanium or titanium alloy blanks with protective coating, After being heated by the first heating furnace, rolling through the first two-roller reversible blanking machine, the second two-roller reversible billeting machine, hot sawing head, finishing rolling unit rolling, double-size flying shear in the section steel production line Segmentation and cooling on the cooling bed, and then heating by the second heating furnace, and then through the straightening machine in the section steel production line to straighten, line up and cold saw machine to cut to length to obtain profiles. Realize the production of titanium and titanium alloy profiles on the small and medium-sized section steel production line, solve the technical problem of steel-titanium collinear production, and provide methods for the economical production of titanium and titanium alloy profiles.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a collinear production method of titanium and titanium alloy profiles and profile steel. Background technique [0002] Titanium and titanium alloy profiles are light in weight, high in strength and superior in mechanical properties. They are widely used in national defense industry and civilian industries such as petroleum, chemical industry, metallurgy, electric power, transportation, medical treatment, marine, environmental protection, construction, sports, tourism and leisure. At present, extrusion molding is usually used in the production of titanium and titanium alloy profiles. Due to factors such as the flow rate of titanium and titanium alloy metal in the extrusion molding process and the filling uniformity of the extrusion cavity, the extrusion molding yield is low, the dimensional accuracy is poor, the production cost is high, and the length of the p...
