After we explained our intentions, the master worker readily agreed to let us visit and learn the whole process of their aluminum chip recycling.
They used a reflective melting furnace, and we quickly drew a drawing of the furnace, measured the dimensions, and looked it very carefully inside and out.
It turns out that the temperature in the aluminum chip furnace is a key, and the higher the temperature, the aluminum chips will become ash powder and cannot be refined into molten aluminum. But when the aluminum chips are red in the furnace, the red aluminum chips should be immediately poured into the large iron pot outside the furnace, at this time, a chemical should be added quickly, a solvent (or catalyst) called sodium fluorosilicate The main function is to reduce the melting point of aluminum, so that the red-hot aluminum chips instantly turn into liquid - this step is the key to aluminum chip recovery.
The master workers passed on these points to us without reservation, and we are very grateful and excited.
After returning to Quyang, we first began a small-scale experiment to turn aluminum chips into molten aluminum.
The factory leaders and workers were extremely happy to see the molten aluminum with their own eyes, and decided to build a recycling furnace immediately.
At that time, our school and the county machinery factory jointly agreed to use the machine factory as a "student work" base for students to carry out aluminum scrap recycling. The factory supplies raw materials, equipment, etc., and the school provides personnel, so that the factory does not increase workers, and the students of the school have a work-study base.
When building the recycling furnace, there was no ready-made place, only a low-lying land at the easternmost end of the machine factory, which was easy to accumulate water, which was not conducive to building a furnace, and some bulky old machine tools were piled up on the ground, which was also very inconvenient to move.
However, these unfavorable conditions and difficulties were all overcome after the hard work of the students! In this way, a furnace and a tall chimney were added to the easternmost part of the factory.

Under my leadership, when the first furnace of aluminum scrap turned into molten aluminum into the mold and formed a large aluminum ingot, people cheered and jumped happily and set off firecrackers! And good news to the leaders of the county government and the industrial department! This also attracted a lot of people to visit!
After hearing the news, the relevant units in the neighboring counties also transported their aluminum chips over and asked us to process them into aluminum ingots. After the normal operation of production, the daily production of aluminum ingots is about one ton, the price of aluminum alloy at that time was 3,000 yuan per ton, our teachers and students worked in the county machinery factory for more than a year, the production of aluminum ingots nearly 1,000 tons, but also to the factory increased a lot of income. At that time, the county machinery factory wanted to give me an aluminum ingot as a souvenir, and I politely declined.

Quyang discovered copper ore?! A chemistry teacher in our school accidentally picked up a few stones in the northern field of Beima Guzhuang Village, and from the appearance, there were yellow and green patina, and after preliminary inspection, it contained copper elements, and he quickly reported the situation to the county party committee and county government.
The county leaders also paid special attention, and later found some similar ores in the original and nearby lots, which inferred that there may be copper mines nearby.
The county has also set up a special copper mining office, and a special person has been transferred to be responsible for this matter, and no one can say how much it contains and whether it can be mined.
At that time, my advice was not to do it blindly, but to invite people from professional geological units to come to the field to survey and appraise.
At that time, the third geological team of Hebei Province was in Yi County in Baoding District, so I was sent to Yi County with a pocket of stone samples. When I explained my intentions, I took out the sample and showed it to the professionals, and they said: This is indeed a copper-containing stone, but the copper content is not high, and it is particularly scattered in the earth's crust, and the professional name is chicken nest mine, which is not worth mining, and there is no way to mine.
Therefore, I reported the results of the geological team to the county leaders, so as to avoid the loss of manpower and material resources caused by blind mining.
