Method for measuring liquid level of tundish

InactiveCN102728802AEliminate overmeltEliminate measurement biasCasting parameters measurement/indication devicesRefractoryBuoy
The invention provides a method for measuring liquid level of tundish. The method comprises the following steps of: connecting the other end of a scale with a length marker to a refractory material buoy with the surface being plated with zirconium oxide; feeding a buoy and the scale into a contact surface between a covering agent and molten steel through a rectangular hole in a tundish cover; dropping a locating cover plate with a central locating hole and a bolt hole at a position covering the rectangular hole of the tundish cover and fixing by bolts; and reading the length displayed by the scale to obtain the depth of the molten steel. The method for measuring the liquid level of the tundish, disclosed by the invention, can not only effectively eliminate problems of super-melting and measurement deviation in an oxygen pipe using process and reduce tundish wastes, but also have fixed position of the buoy, exact measurement result and audio-visual scale display, and can exactly measure and feed back the liquid level of the tundish in real time so as to provide reliable evidence for pouring stoppage and deceleration, thus the loss in a pouring stoppage process is largely reduced, the yield of the molten steel is increased, and the personal safety of operators can be ensured at the same time.

Method and apparatus for indicating a load

The present invention provides an innovative method and apparatus for determining continuous, visual clamp load status during tightening and throughout the life of a fastener. The present invention provides a pair of levers suitably configured and positioned within a fastener to provide an amplified indication of the deformation of the fastener as a load is applied to the fastener. In accordance with one aspect of the invention, a first lever is connected at an internal pivot point of a cartridge with the lower end of the first lever resting upon an abutment within the fastener, while the upper end displaces the lower end of a second lever such that movement of the upper end of the second lever is amplified with respect to movement of the lower end of the first lever. As the fastener is tightened, the fastener will elongate causing the abutment to move away from the lower end of the first lever. As the abutment moves, the first lever pivots or rotates causing the upper end or indicator of the second lever to move relative to a visual scale that is calibrated to indicate clamping force. The cartridge carrying the two levers is inserted into the fastener with the lower end of the first lever being displaced by the abutment a distance corresponding to a preselected elongation of the fastener, placing the indicator end of the second lever at the lower vales of the indicator scale. As the fastener is tightened, elongation of the fastener causes displacement of the abutment and a movement of the indicator up the indicator scale. If the fastener loses tension, the fastener will contract and the abutment will again displace the lower end of the first lever, rotating the indicator end of the second lever toward the lower values of the indicator scale. Assembly and calibration of the device requires the simple, inexpensive process of advancing the cartridge within a central bore in the fastener.
