Embodiment Construction

[0020] The sintered molybdenum billet with a net weight of 25 kg of Φ50~53×1300 mm is placed in front of the push rod in front of the furnace by the billet feeding mechanism, and pushed into the induction heating furnace (the current is zero when there is no material in the furnace); the furnace can Two billets are placed, and the temperature of the material is controlled by the feedback of the photoelectric thermometer. One can be pushed out every 3 minutes (the heating time of each molybdenum billet is 6 minutes); It is pulled out from the furnace mouth at a speed of m / s, and quickly sent to the rough rolling mill for rolling. The rough rolling start temperature is 1400-1500°C; The size is a hexagonal or round wire rod with an inscribed circle diameter of 16.2 mm, and the temperature drops to 1150-1200 °C. Its deformation resistance is also increased from 50MPa at the beginning of rolling to 220MPa, and the maximum elongation coefficient is also reduced from 60% to 7-8%. If...

Abstract

The invention relates to a large unit heavy molybdenum, tungsten and titanium bar and a wire coil proximate matter, and adopts the manufacture method that heavy ingot cogging is adopted, on-line continuous heating and rolling is adopted without stop during the machining process, and long wire drawing is adopted during the finish rolling process. The invention mainly comprises an automatic bar material feeding machine, a medium-frequency induction sintering bar heating furnace, a feed adding mechanism, a three-roll Y type 10 stand roughing mill group, a tube-type conveying mechanism, an on-line three section superaudio induction heating furnace, a three-roll Y type 12 stand finishing mill group, the tube-type conveying mechanism, a recoiling machine, and an electronic control and fume extraction system. The large unit heavy molybdenum, tungsten and titanium bar and the wire coil proximate matter are the important raw material in the electric light source industry, the automotive industry, the glass industry and the machinery manufacturing industry.

Description

technical field [0001] Metal Press Manufacturing Background technique [0002] Molybdenum, tungsten rods and wires are important raw materials for electric light source, automobile industry, glass industry and machinery manufacturing. At home and abroad, products with a single weight of about 12 kilograms are the most produced, and it can be seen from the product metallographic structure that the product quality cannot meet the ideal requirements. So far, the production process of molybdenum, tungsten and titanium rods and wires at home and abroad mainly Swivel-stretch or rolling-stretch two production methods. [0003] Swivel-drawing is the traditional production method for molybdenum, tungsten and titanium rods and wires. This method: the equipment used is simple and the investment is small, but due to the limitation of the performance and operation of the rotary forging machine, generally only small sintered billets with a single weight of about 1 kg can be processed; ...
