Abstract

The utility model provides a tundish accident early warning device is the temperature measurement hole that has bored certain quantity on the outer box hat of tundish, has all installed temperature measuring device such as thermocouple in the temperature measurement hole, and temperature measuring device is connected with the temperature measuring instrument who installs the monitoring box on the tundish car respectively through the wire. Once the temperature of the steel shell outside the tundish abnormally rises, the temperature of the steel shell outside the tundish is immediately reflected on the temperature measuring instrument, and alarm information is displayed and sent, so that the whole steel casting process of the tundish can be controlled, accidents can be eliminated in germination, the use reliability of the tundish is improved, the safety of personnel and equipment is ensured, and meanwhile, a reliable basis is provided for a tundish quality evaluation system.

Description

Tundish accident warning device

technical field

The utility model belongs to a safety monitoring device for steelmaking equipment, in particular to an accident prevention and alarm device for continuous casting machine tundish drawing steel.

Background technique

The tundish used in continuous casting in steelworks usually consists of an outer steel shell, a permanent lining and a working lining. In the process of continuous casting and pouring steel, once the working lining falls off, the brick lining drills steel, etc., if it is not discovered in time, there will be a major danger of molten steel escaping, which will pose a great threat to personal and equipment safety. And the tundish used at present all does not have the pre-alarm measure of this type of accident without exception.

Observation of the tundish after field use found that most of the problems with the working lining of the tundish occurred in the molten steel injection area, and there were also unsafe factors in the area near the submerged nozzle of the tundish, and this area was close to the operator , is an obvious source of danger, once an accident occurs, the consequences will be disastrous.

Contents of the invention

The purpose of the utility model is to provide a tundish accident warning device which is simple, easy to operate, and can improve the reliability of the tundish use and ensure no safety accidents.

For this reason, the technical scheme that the utility model takes is:

An early warning device for tundish accidents. A certain number of temperature-measuring holes are drilled on the outer steel shell of the tundish. Temperature-measuring devices are installed in the temperature-measuring holes. The temperature meter in the monitoring box is connected, and the temperature meter is connected to the alarm.

The temperature measuring device is a thermocouple.

The beneficial effects of the utility model are:

Since the accident warning device is installed on the outer steel shell of the accident-prone area of the tundish, once the temperature of the outer steel shell of the tundish rises abnormally, it will be immediately reflected on the temperature instrument in the monitoring box, and the temperature instrument will display through the alarm And send out alarm information, so that the steel pouring process of the tundish can be controlled throughout, and the accident can be eliminated in the bud, the reliability of the tundish can be improved, and the safety of personnel and equipment can be guaranteed. At the same time, it also provides a reliable basis for the tundish quality evaluation system. The utility model has a simple structure, is convenient to grasp and operate, and does not require more investment, and the effect can be seen quickly.

Description of drawings

The attached drawing is a schematic diagram of the installation and use state of the tundish accident warning device.

In the figure: monitoring box 1, tundish 2, outer steel shell 3, wire 4, temperature measuring hole 5, tundish car 6.

Detailed ways

Below, the utility model is further described in conjunction with accompanying drawing.

As can be seen from the accompanying drawings, the utility model is mainly made up of a monitoring box 1, a temperature measuring device and a connecting wire 4; a thermometer and an alarm are installed in the monitoring box 1, and the temperature measuring device adopts a thermocouple. The specific method is: first drill a certain number of temperature measuring holes 5 on the outer steel shell 3 of the problem-prone area of the tundish 2 . For example, drill 8 temperature-measuring holes 5 at the middle upper part of the outer steel shell 3 respectively, and then drill 4 temperature-measuring holes 5 at the lower corners on both sides of the outer steel shell 3. Next is that tundish 2 is packed in the tundish car 6, and then the temperature measurement monitoring box 1 that the thermometer and the alarm connected with it are housed are fixed on the front column of the tundish car 6. Then, insert the thermocouples into the temperature measuring holes 5 one by one, and connect the thermocouples and the thermometer with the wire 4 .

Claims (2)

1. tundish accident early warning device, it is characterized in that, outside tundish, be drilled with the thermometer hole of some on the box hat, all be equipped with the thermometric device in the thermometer hole, the thermometric device respectively by lead be installed in the middle of thermometer in the monitoring box on the hired car is connected thermometer connection alarm.

2. tundish accident early warning device according to claim 1 is characterized in that described thermometric device is a thermocouple.
