Problems solved by technology
However, because lead is relatively difficult to process, most of the lead is processed by mold filling process at present, that is, the lead is first heated to melt and then poured into the mold. This traditional process is prone to leakage, and it is difficult to ensure the filling The compactness of the lead-in greatly affects the product quality

Embodiment 2
[0042] see image 3 , image 3 The lead filling method for preventing lead leakage provided by the embodiment of the present invention comprises the following steps:
[0043] Step 301, divide the lead block to be processed into two parts, the first part has more weight, and the second part has less weight, and these two parts will be processed differently in the subsequent process.
[0044] Step 302: Load the first part of lead weights with relatively large weight into the holding device.
[0045] In this embodiment, the holding device adopts hollow cast iron, such as figure 2 As shown, there is a lead filling opening on its upper surface, and the specific structure, size and specific position, size and shape of the hollow cast iron opening are not limited to figure 2 As shown in , it can be designed according to the current needs.
[0046] Step 303 , place the leaked cast iron filled with lead weights in a heating furnace for heating until the lead weights therein melt ...

Abstract
The invention discloses a lead pouring method preventing the lead leakage phenomenon from appearing, and belongs to the technical field of metal material processing. The lead pouring method includes the steps that to-be-processed leads are divided into a first part of leads and a second part of leads; the first part of leads are put into a containing device; the containing device is heated till the first part of leads of the to-be-processed leads are melted to stop heating; after the first part of leads in the containing device are cooled and submerged, the second part of leads are added into the surfaces of the obtained first part of leads, heating is carried out on the surfaces till the leads are melted to stop heating. According to a new lead filling technology, the leads are put into hollow cast iron in batches and heated in different modes, the leads after being heated and cooled in the hollow cast iron are also beaten, the lead pouring leakage phenomenon can be effectively reduced, processing is easy, and the processing difficulty is reduced; in this way, manufacturers can trustingly adopt metal material leads with the same anti-radiation effect, the light relative quality and the low cost to replace tungsten in the production process, and the production cost is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of metal material processing, in particular to a lead filling method for preventing lead leakage. Background technique [0002] At present, the metal materials lead and tungsten both have good radiation protection function. Among them, lead is a metal extracted earlier by human beings. It is the softest heavy metal and one of the densest metals. It has good ductility and is easy to make alloys with other metals. Lead alloys are widely used in the manufacture of lead-acid batteries. Plates, lead pipes and lead plates are used as protective materials. Tungsten is a relatively rare metal and the most refractory metal, with a melting point as high as 3410°C. Under the same volume, compared with the metal material lead, the metal material tungsten has the disadvantages of high quality and high cost, so lead has a great market prospect. However, because lead is relatively difficult to process, most of the lead ...
