石墨坩埚又称碳素坩埚，是一种金属冶炼器皿，采用天然石墨为主体材料，根据石墨坩埚的材质，选用不同的生产制造方法。石墨坩埚有塑性成型生产工艺和压制成型生产工艺两种，压制成型石墨坩埚，需配模具，在四柱液压机的作用下，一次模压成型。可压制圆形石墨坩埚、方形石墨坩埚、多孔型石墨坩埚，常用800吨、1000吨、1500吨、2000吨、2500吨等，公司可根据石墨坩埚规格尺寸，设计生产所需石墨坩埚成型液压机的工作台面、开口、行程等。
In order to improve the production efficiency, the 2000-ton graphite crucible forming hydraulic press adopts double-station work in turn, with automatic operation, high production efficiency and fast speed. The equipment has a stroke of 1800mm and an opening of 3500mm. It is equipped with a mobile worktable, LC control system and servo numerical control system, which improves the production efficiency and machining accuracy. The main cylinder usually adopts single-cylinder or double-cylinder structure, and the force is concentrated without partial load. The oil cylinder is equipped with a fast stroke filling device to support the rapid descent of the sliding beam and improve production efficiency. The column is made of high-quality solid round steel after being polished by a lathe, and then subjected to intermediate frequency quenching, fine grinding by a cylindrical grinder, chrome plating and other treatments to ensure the hardness and strength of the column surface, not easy to scratch, and the column is not easy to deform under high pressure. Demoulding adopts multi-stage hydraulic system, which can smooth demoulding and ensure the density of crucible. The large diameter graphite crucible with a diameter of 60cm ~ 150cm can be pressed, the molding texture is more uniform, the density is higher, and it can withstand the high temperature of 1500~1800 ℃. It has the advantages of simple process, short production cycle, high yield and efficiency, low labor intensity, low molding moisture, low crucible shrinkage and pore rate, and high product density.
Features of 2000 tons graphite crucible forming hydraulic press:
(1) Hydraulic system, electro-hydraulic control and accurate hydraulic two-way sequential high and low pressure operation system, high pressure, fast speed, low power consumption and low noise.
(2) The double-station 2000-ton graphite crucible forming hydraulic press integrates mechanical and electrical fluids, automatically circulates when it is started, multiple action programs are interlocked, and pressure is automatically distributed. Different crucible hydraulic presses, crucible forming machines, and crucible hydraulic press equipment can be customized according to customer needs.
(3) It can realize two molding processes of constant pressure and fixed range, with pressure holding delay function and adjustable delay time. The working pressure and stroke can be adjusted within the specified range.
The double-station 2000-ton graphite crucible forming hydraulic press is suitable for crucible pressing and forming, including graphite crucibles, refractory crucibles, quartz stone crucibles, silicon carbide crucibles, corundum crucibles, alumina crucibles, etc. The double-station graphite crucible forming 2000-ton four-column hydraulic press is mainly suitable for crucible pressing, pushing out and demolding to complete the process continuously.
