This utility model discloses a clamping fixture suitable for high-temperature tensile testing, relating to the field of tensile equipment technology. It includes an environmental chamber body and a threaded round bar. Hydraulic telescopic rods are installed on the inner walls of both the upper and lower ends of the environmental chamber body via tension sensors. Connecting blocks are connected to opposite ends of the two hydraulic telescopic rods, and tie rod structures are connected to both connecting blocks. Each tie rod structure has a slot, into which a clamp head is inserted. The clamp head has threaded holes, and both ends of the threaded round bar are screwed into the two threaded holes respectively. In this utility model, the clamp head is installed and removed through the insertion and engagement of the clamp head and the slot, allowing for the loading and unloading of the threaded round bar outside the environmental chamber body. By loading and unloading the clamp head and sample as a whole inside the environmental chamber body, the purpose of conducting high-temperature tensile tests can be achieved quickly and safely, significantly reducing the operation time inside the environmental chamber body, thereby reducing temperature loss and greatly improving testing efficiency and safety.

This invention discloses a gold extraction process and system using whole-sludge cyanidation without pre-concentration, relating to the field of gold beneficiation and smelting technology. It solves the problems of low grinding efficiency, complex processes, difficulty in recovering coarse gold particles, and high safety risks in existing processes. The process includes raw ore crushing, primary grinding, gravity separation, hydrocyclone classification, secondary grinding-leaching, leaching-adsorption, smelting, and tailings treatment; the system includes corresponding crushing, primary grinding, gravity separation, hydrocyclone classification, secondary grinding-leaching, leaching-adsorption, smelting, and tailings treatment units. The key innovation is: gravity separation recovers coarse gold particles after primary grinding; the secondary stage uses an azin mill to achieve synergistic grinding-leaching, eliminating the pre-concentration stage; and the filtrate reagents are recycled. This invention features a simplified process, low energy consumption, high gold recovery rate, and safe and environmentally friendly operation, suitable for gold extraction from gold ores containing coarse gold particles that require fine grinding.
