Abstract

The invention discloses a weighing device applied to a high-temperature working environment. The weighing device comprises a weighing sensor and a hook. A water-cooled thermally-insulated cover with an open upper end is arranged outside the weighing sensor and is a water-cooled box; the lower end of the weighing sensor is fixedly connected with the inner bottom surface of the water-cooled thermally-insulated cover and the lower end of the water-cooled thermally-insulated cover is fixedly connected with the upper end of the hook by a water-cooled lower connecting rod. A shackle is fixedly connected to the upper end of the weighing sensor; a water-cooled lifting rod is fixedly connected to the upper end of the shackle; a water-cooled thermally-insulated cover plate sleeves the outside of thewater-cooled lifting rod fixedly; a water inlet and a water outlet is formed in the upper end of the water-cooled thermally-insulated cover plate; and the water inlet of the water-cooled thermally-insulated cover plate is communicated with the water inlet of the water-cooled thermally-insulated cover by a first hose. Therefore, the stability and weighing accuracy of the weighing sensor during online high-temperature hot base weighing are improved; the service life of the sensor is prolonged; and the weighing device is easy to maintain or repair.

Description

technical field [0001] The invention relates to the technical field of weight detection, in particular to a weighing device adapted to high-temperature working environment conditions. Background technique [0002] In order to improve the finished product rate of the bar factory and reduce the non-cut rate, it is the basis to improve the qualified rate of continuous casting slab fixed weight. The stability and weighing accuracy of the on-line weighing sensor are one of the main factors affecting the pass rate of billet weighing. Therefore, how to improve the stability and weighing accuracy of the load cell under the conditions of long-term high-temperature slab thermal radiation and rapid changes in ambient temperature is an important issue to be solved. Although the heat shield is designed outside the load cell used in the existing steel mills, due to the continuous long-term heat radiation of each high-temperature hot billet (~900°C) to the heat shield, the heat shield bec...
