Abstract
The invention discloses a device for measuring elongation percentage of stainless steel on line, and belongs to auxiliary facilities in metallurgical production. The device consists of two vertical measuring bars with scale marks and a horizontal cross bar, wherein the cross bar is made of an alloy material; and the device is characterized in that one end head of each measuring bar is fixedly provided with a punch head. The method for measuring the elongation percentage comprises the following steps of: finding the horizontal position of a steel plate under the condition that the steel plate generates tension; punching points on the surface of the horizontal steel plate with the punch heads of the two measuring bars; measuring the distance between the punched points; measuring the distance between the punched points on the surface of the steel plate again after the steel plate is stretched; and calculating the specific value of the steel plate before and after the stretching. The device has the advantages of simple structure and low manufacturing cost; and the measurement method has the advantages of simplicity and low error in the measured elongation percentage.
Description
Technical field:
The utility model belongs to the auxiliary equipment of metallurgical production.
Background technology:
The method of on-line measurement stainless steel extensibility is by drawing point measurement on steel plate at present, and this metering system can accurately not read extensibility numerical value, can not well feed back true horizon, quality improvement is not had the effect of directiveness.
Summary of the invention:
In order to improve the accuracy of measurement, the utility model provides a kind of device and method of on-line measurement stainless steel extensibility.
The present invention includes measurement mechanism, measurement mechanism is made of the cross bar of two vertical mark posts that have the scale sign and a level, and cross bar is that alloy material is made, and it is characterized in that a termination of each mark post is installed with drift.
The method that adopts said apparatus to measure the stainless steel extensibility realizes by following step:
1. build up under the situation of tension force at steel plate, seek the horizontal level of steel plate;
2. use drift striking point on the surface of horizontal steel plate of two mark posts;
3. measure the distance between striking point;
4. steel plate stretched after, in the distance of surveying once more on the surface of steel plate between striking point;
5. calculate the ratio of steel plate stretching front and back.
Present device is simple in structure, and cost of manufacture is low, and measuring method is simple and measure to such an extent that the extensibility error is less.
Description of drawings:
Fig. 1 is the structural drawing that the present invention measures the device of stainless steel extensibility.
1, mark post, 2, cross bar, 3, drift.
Embodiment:
Embodiment: shown in Figure 1, measurement mechanism of the present invention is made of the cross bar 2 of two vertical mark posts that have the scale sign 1 and a level, it is characterized in that a termination of each mark post is installed with drift 3.
The method that adopts said apparatus to measure the stainless steel extensibility realizes by following step:
1. utilize the idler roller of the common equipment straightener of smelter to build up at steel plate under the situation of tension force, seek level value; Promptly be with steel to enter before the straightener, set up tension force by 6 bridle rolls;
2. between jockey pulley and accumulator, hold up two mark posts, hit with the upper surface of drift at steel plate, make steel plate produce a pair of static striking point or pit, be convenience of calculation, each is round values (this example is 1000mm) to the distance between static striking point, and promptly the distance between two drifts is 1000mm;
Illustrate: striking point can be in lengthwise position or the both sides portion position or the centre position of steel plate.
3. after stretching through the idler roller of straightener, drawing process carries out between two accumulators, measure the dot spacing that 2. hit in the step from, be 1005mm.
4. calculate the front and back ratio that stretches.
Distance before stretching between striking point is 1000mm, and the distance that stretches between the striking point of back is 1005mm;
Steel plate extensibility=(back distance-stretching front distance stretches)/stretching front distance * 100%
＝(1005-1000)/1000×100％
＝0.5％
