Embodiment Construction

[0018] Referring to Fig. 1, the rapid assay device of the present invention is divided into two parts, a base 1 and a cover plate 2. The cover plate 1 includes a funnel 3 having a certain height h and half of a horizontal pipe 4, and the other half of the horizontal pipe 4 is located at the base. In the seat 1 , that is, the central cross-section passing through the center of the horizontal pipe 4 is located on the joint surface of the base 1 and the cover plate 2 . This structure is convenient for disassembly and assembly, and can conveniently pour out the cooled solid slag.

[0019] The working principle of the present invention is as follows: It can be seen from the principles of heat transfer and fluid mechanics that when the melt flows into a certain horizontal pipeline at a certain speed, the melt gradually solidifies due to heat dissipation, and the length of the flow path of the melt in the pipeline before solidification is It is related to many factors: from the proce...

Abstract

This invention discloses one resides sticky rapid rest method and its device, which comprises the following steps: measuring melt pool resides temperature; drilling the resides into funnel; the funnel exit end sets one level tube to test melt resides level tube flow length; according to the measured flow length to get relative temperature melt resides sticky degrees on standard curve.

Description

technical field [0001] The invention relates to a method and a device for quickly measuring the viscosity of high-temperature slag produced by fire smelting equipment such as copper, lead, and zinc. Background technique [0002] In the fire production process of copper, lead, zinc, etc., the viscosity of slag is an important comprehensive index that marks the working condition of the production equipment. When the viscosity of the slag is small, the metals in the slag are easy to settle and separate, and the slag contains less valuable metals, and vice versa. Therefore, it is desirable to control the viscosity of slag at a lower level during production. The current method for measuring the viscosity of molten slag has a long period (when measuring the viscosity of molten slag with a rotary viscometer, it takes more than 10 hours for each sample), high cost, complicated operation, and cannot meet the needs of the production site, so it is necessary to Develop a method and d...
