Problems solved by technology

The disadvantage is that the surface quality of the rolled molybdenum rod is not good, which affects the quality of the subsequent drawing; and the unit weight of the φ1.0mm molybdenum wire depends on the weight of the molybdenum billet, which can only reach a level of less than 25kg at present

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The molybdenum wire production continuous rolling and continuous forging billet opening equipment of the present invention includes a super-audio frequency induction heating furnace, a 265 "Y" type rolling mill, two rotary forging machines, a butt welding machine and three rotary forging machines arranged in sequence. Its production process see image 3 , the metal molybdenum billets with a single weight of about 2.5kg-5kg are sent to the super-audio frequency induction heating furnace to be heated to a temperature of 1500-1550°C, and the heated metal molybdenum rods are immediately sent ...

Abstract

The invention relates to molybdenum wire production continuous rolling and continuous forging cogging equipment, which comprises a heating furnace, a rolling machine, a first rotary forcing unit, a butt-welding machine and a second rotary forging unit arranged in sequence. The invention further relates to a method for producing a molybdenum wire with the equipment. By adopting a continuous rolling and continuous forcing process in which the advantages of cogging of the rolling machine and a plurality of rotary fogging machines are combined, the investment cost is greatly reduced, production efficiency is increased, consumption is lowered, and yield is increased. Meanwhile, the automatic control degree is high, noise is small, a good dust collecting effect is achieved, working environment conditions can meet relevant industrial sanitation and environment requirement standards, and the product quality can reach the world advanced level.

Description

technical field [0001] The invention relates to a molybdenum wire production continuous rolling continuous forging equipment and a production method thereof. Background technique [0002] Molybdenum is a rare and precious metal with a high melting point. It has many excellent physical, chemical and mechanical properties. It is an important non-ferrous metal raw material and an irreplaceable strategic substance. my country's molybdenum resource reserves are very rich, ranking first in the world; my country's production of molybdenum wire also ranks first in the world. The core technology of molybdenum wire production is the adoption of advanced and reasonable blanking process. [0003] The first issue of "China Molybdenum Industry" magazine in 2008 published the article "The latest progress of domestic molybdenum smelting and processing technology", which gave a detailed description and objective evaluation of the existing molybdenum wire production technology at home and ab...
